Codes for Ethnic or Language Identification

The following codes for language or ethnic group are found in columns
33-34 of the title records in the
Master File, and in columns 10-11 of the Thirty-Year File. Codes are
shown only for those countries with more than one language group identified
in the data. The two-digit number preceding the country name is the
country identifier found in columns 1-2 of both files.
